.SHORT TERM...Today through Tuesday night...A short wave trough
will move toward and then over the state today into this
evening. This will likely produce a greater coverage of
thunderstorms than we have seen the past few days. SPC has
placed roughly the southern half of the CWA in a marginal risk
for severe weather, with winds being the main threat. Storms
were ongoing mainly over the mountains of SW Idaho with isolated
storms in SE OR as of 0745Z. New development is expected around
18Z today, with storms moving northeast around 25 mph. Storms
should exit the area around midnight Sunday night. Weak ridging
aloft will move in Monday behind the departing trough, followed
by zonal flow Tue and Tue night. These features will keep us dry
and warm (roughly 10 degrees above normal) both days.

.LONG TERM...Wednesday through Sunday...Zonal flow Wed will
become SW Thursday and Friday, keeping us warm and dry. Models
are consistent in depicting an upper level trough moving into
the PacNW Friday night through Sunday, but differ in important
ways on the details. At this time, the most likely solution is
one with the low staying to our north, keeping us dry. We should
be warm Friday, with temperatures cooling to near normal Sat
and perhaps below normal Sunday.

.AVIATION...Mainly VFR. An area of showers with weak embedded
thunderstorms will move northeast toward KMYL through 09/12Z,
with isolated TRW still developing in SE OR. The strongest
showers/storms could have brief MVFR conditions and gusts to 45
kt. As of 0745Z, there is a gust front associated with the area
of showers/storms that is producing widespread gusts to 35 kt
over SW Idaho, and is about to move through KMUO and then head
toward the western Magic Valley. Sfc winds: mainly W through N
5-15 kt. Winds at 10k ft MSL: S 5-15 kt this morning, becoming
SW to W this afternoon.

KBOI...VFR. Surface winds N to NW 15-25 kt through 09/10Z, then
NW 5-15 kt. Light rain showers possible Sunday. Confidence in
the formation of afternoon thunderstorms is low, with a 15%
chance of a storm within the vicinity of the airport.
